Acoustic Phonetics

Sound waves
Acoustic correlates
- Frequency (pitch)
- Intensity (loudness)
Acoustic measurements
Acoustics of vowels
- Complex tone
- Formants
- F1 X F2 plots
Stops
- Release burst, aspiration, VOT, stop gap
Nasals
Fricatives
Approximants
Connected speech
Suprasegmental aspects
- Pitch, intensity contours
- Acoustic correlates of stress

Objectives

Label axes of waveforms and spectrograms correctly
Define pitch and frequency and explain how they are related
Define loudness and intensity and explain how they are related
Segment speech signals into component phonemes
Describe F1 and F2 formant patterns for corner vowels /a/, /i/, and /u/
Label corner vowels in spectrograms and F1 X F2 plots
Use acoustic cues to identify manner of articulation in spectrograms and waveforms
Use acoustic cues to differentiate between voiced and voiceless stops and fricatives
Use acoustic cues to determine place of articulation for stops and fricatives
Segment waveforms and spectrograms of short utterances
